Hello,

If you got 80 in your OUAT examination then it's good. Last year the general category cutoff was 71.333.

And you mentioned that you are also OBC category candidate belongs with green card. So it's very easy to get a college.

But admission in OUAT Bhubaneswar University have some criteria. Like-

1. You have to score minimum 69% in OUAT exam.

2. Your 10th and 12th grade always above 90% or 95%.

3. If your 10th and 12th grade is low then you will score high in OUAT examination.

You are already said that your grade in 10th and 12th. 10th grade is higher than 90% but your 12th grade is low. So it's difficult to predict us that you are getting this college or not.

Actually agriculture mainly based on your 10th and 12th board examination marks. But you can try for it because every year cut-off marks will differ.
